Simon Helsen commented on JENA-97:
----------------------------------
I see the problem in both old-style and transactional TDB, but I do see replicated bindings.
I have to check if tdbquery removes these duplicates and if that is expected. I can confirm
that TDB 0.8.7, there were never any duplicates in the returned bindings.
> TDB 0.9.0 snapshot sometimes returns a SELECT binding twice

> Very sometimes (rare), it seems that a result set will repeat the first SELECT binding.
E.g.
> SELECT ?a ?b ...
> will bind ?a twice in the result set. It only happens quite rarely, but the same queries
behave correctly in TDB 0.8.7.
